BRAKE-HEAD.

Specification of Letters iatent.

' Patented March 24', 1903.

' Application filed June 21, 1907. Serial No. 380,173.

To all whom it may concern:

Be it known that we, CHARLES E. GOSNELL and ADAM M. HARRIS, citizens ofthe United States, residing at Keyser, in the county of Mineral andState of West Virginia, have invented new and useful Improvements inBrake-Heads, of which the following'is a specification.

The present invention relates to brake shoes for railroad cars, andrelates more particularly to safety devices for preventing the brakeheads from''' dropping off their hangers in the event of the shoesbreaking or becomin detached, thus preventing the heads from roppingupon the rails and causingrde'railment of the train. p

he'invention has for one of its objects to improve and simplify theconstruction of brakes so as to be comparatively easy and in- ;ex ensiveto manufacture, thoroughly relia le and eflicient in use, and readilyadapted to brake heads of standard form.

A further object of the invention is theprovision of a brake, headhaving means ar-- ranged to engage the hanger or link that suspends thehead from the brake beam, said erating to prevent the headfrom being joted off the hanger in case the shoe becomes broken or detached. 1

Another object of the invention is to provide a safety device inthenature of an attachment, whereby the devicecan be a plied to brakeheadsof standard form and a ready in use.

With these objects in view and others, as

will appear as the description proceeds, the

invention comprises the various novel features' of construction andarrangment of arts which will be .more fully described ereinafter andset forthwith particularity in the claims ap ended hereto. vv.4

In the accompanying drawings, whlch illustrate certain of t showing the'mddified form of attachment.

Fig. 7 is; a perspective view of theattachment shown 1n hanger and drops on the track the-retaining means orkee since the lugs eng e embodiments of the invention, Figure 1 isasperspective viewi ofia. brake provided with one form of retaining"Fig. 3. attachment shown in Fig. 4.

Similar reference characters are employed to designate correspondingparts throughout the several views. v i 1 Referring to the drawings, A-designates the head or body of the brake; B, the shoe; 0., the link orhanger; and D, the key for locking .the shoe andhead on-the hanger,these parts.

being of standard construction. The shoe B has a transverse boss 1extending from its head A, and the sprin key passes through apertures 3and 4 In t e boss I and webs 5 on the head that engage on opposite sidesof a the boss.

forms a bearing 6 in which engages the The inner end ,of the recess 2hanger C, and since the shoe B closes the open side of the recess, theparts of the brake are held on the ban er in 006 erative relation withthe wheel of t 1e car. t often happens that the key D breaks or joltsout of place, thereb permitting the shoe to be released, and w en thisoccurs, thehead jolts off the directly in front of the-succeeding wheelof'the car; thus ca'iising a. derailment of the train. f To prevent thehead'from dropping off the hanger, suitable retaining means areemployed. Accordin to one'form of the invention, the head is cast orotherwise pro vided with one or more lugs or projections 7 locatedslightly above the bearing 6 and in front of the same to engage thefront side of the hanger C. These lugs can be made round, as shown inFig. 1 or provided with -fiat sides 8, as shown 1n Fig. 2. In case-thelqey or. shoe of the brake became broken, the headwould tend to drop offthe hanger in a direction away from vthe adjacent wheel, but

rs prevent this, e the si e members of the link or hanger and old thehead in place.

.3. The retaimn means is readily adapted for use as anattac ment forbrake shoes already in use, and one form of the attachment, as shown in.Figs. 3, 5 and 7, comprises apiate 9 having and ribs, or fian es 10 thatare adapted; to engage the side e ges'of the upper arm 11 of the head,and on t e ribs are ugsn; 12, that are adapted to engage revent theh'eadfrom becoming displaced.

he attachment=may be secured to the head in any suitable manner, "asforinstance", by

Fig. 8 isa perspective viewof the rear side that engages in a recess 2of the the hanger-tor" 1'05 not provided with bolt-receiving a ertures,'the attachment can beclamped in p ace by a key for detachably connectingthe shoe with bolts 13 passing through registering apertures 14 and 15in the plate portion 9 and head A, respectively. The attachment isapplied to the head before-the shoe and key are applied, as will bereadily understood;

In the attachment'shown in Figs. 4, 6 and a, a clamping piece 16 issecured to the plate portion 17, the said clamping iece cooperating withthe L- haped or over anging lug 18 for holding the attachment on thehead, as clearly shown in Fig. 6. In casejthe head is single bolt 19, asshown in..Fig. 4, the said bolt passing through the terminal extension-20 on the plate portion 17 and through the base of the clamping member.If the head is provided with bolt-receiving apertures, an

additional bolt 21, Fig. 6, may be employed for clamping the partstogether. in this embodiment, the extension 20 serves as one of theretaining lugs or keepers, and on the hook-shaped extension 18 is formedI the other retaining lug or keeper 22.

From the foregoing description, taken in connection with theaccompanying drawin s,

the advantages of the construction and of t e method of o eration willbe readily apparent to those skiliied in the art to which theinvention'appertains, and while wehave described the principle ofoperation of the invention,

1. Av brake comprising a head, a shoe, a

I the head, and a hanger on which the head is held by the shoe, incombination with means inde endentv of the key for preventing the heafrom becoming detached from the hanger in the event of the key droppingoutor detachment of the shoe.

. 2. A brake'comprising a head, a shoe, means for detachab'ly connectingthe shoe with the head, and a hanger on which the head is held by theshoe, in combination with means onthe head independent of thefirstmentioned means for engagement with the han er to prevent the headfrom dropping ofi t e latter in the event of detachment of the shoe. g

'3. The combination of' a hanger, a brake pivotally mounted thereon andincluding a head, and'means on the head located adjacent the portion ofthe hanger on which the brake-swings for preventing accidentaldetachment of the head. r

4. .The combination of a linkshaped hanger, a brake comprising a headand shoe deta c-hably connected and mounted on the link, and laterallyextending members on the head arranged to engage the link for preventingthehead from dropping ofi the latter.

5. Thecornbination' ofa head, a shoe, a

key forconnecting the'shoe and head, and a hanger on which the head ismounted, with an attachment applied to the head for pre-,

venting the latter from dropping off the hanger in the event of breakageor displace ment of the key.

6.'An attachment for. brakes comprising a body, oppositely extendinghanger-engaging members on the body, and means for attaching the bodytoa brake. 7. An attachment of the character described comprising a bodyhaving a hookshaped extension at one end, a clamping 1 piece cooperatingwith the said extension for securing. the attachment to a brake, andhanger-engaging means on the said body.

- 8. The combination of a brake head, a

member extending across the same, fastening devices for securing themember to the head, and devices on the extremities of the member forengaging the hanger of a brake. In testimony whereof, we afiix our signatures in presence of two witnesses.
